Guide ranges for supply & fit; controls and commissioning by a smoke-control specialist. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building control fees, where a job needs them, are shown as their own line.
Towns we list in Cheshire
We work right across England, and Cheshire is covered on the same footing as everywhere else. There is no showroom or depot to visit. The survey happens at your property or, for fit-only jobs, from your photos. If your address is remote or reached by ferry, tell us early and we will confirm what arrangement is needed before quoting.

What we do on the day
- Existing vent, actuator and upstand surveyed with the specialist
- Upstand checked, adapted or rebuilt to the vent maker's drawing
- Old vent removed with the stairwell kept protected below
- Fire rules near escape routes — We check the roof around the vent for fire rules that affect it.
- Controls and backup power — We confirm the controls, detection and backup power are being dealt with by a specialist.
Rules that apply in England
A replacement smoke vent in England has to keep the free area and performance the building's fire strategy relies on, using a vent certified to BS EN 12101-2 with its actuator and backup power. We fit the vent and do the roof work; a smoke-control specialist connects and commissions the controls, and we confirm whether building control needs to be notified.
Common questions in Cheshire
What upstand height and roof pitch does smoke vent rooflight fitting need?
It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
Can you remove and dispose of the old rooflight?
Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.
Can you fit a rooflight in winter or when it is raining?
Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.
